ENVIRONMENT
This invention regards a method of determining the effect of a spill on a marine environment. More particularly, it , regards a method in which living organisms are placed at an appropriate distance and position from an object to be monitored, and where the living organisms are fitted with instruments for physiological and behavioural measurements and are monitored in real time to register spills. The online signals from the instruments are compared with physical and chemical measurements of water quality and the known behavioural pattern of the organism to detect the occurrence of an accidental spill, and to determine whether the effect of the spill on the marine environment exceeds a predefined acceptable limit. If the online monitoring indicates a probability of unexpected spills or spills that exceed the accepted limit, the measurements are validated by taking samples of the organisms to measure their state of health.
Spills from port facilities, offshore installations and ships can cause damage to the local marine environment, which damage may take a long time to rectify. Although so-called "zero discharge" may be the aim, with "zero discharge" being
2 defined as no discharges to the sea or no discharges of substances that are harmful to the environment, accidental spills may occur, and knowing the effect of the spill on the surrounding marine environment will be of great importance when it comes to determining the severity of the spill and deciding on what, if any, action to take. In addition, it would be of interest to be able to prove that the effect of any permitted discharges is no greater than that which is already anticipated.
In most marine environments there is so-called background pollution which may be natural or may have been brought into the area from other areas.
Thus, when a spill occurs, it will be difficult to determine whether measurement values from samples taken after the spill represent background pollution or the present spill. In addition, these measuring results will generally not be available for quite a while after the spill has occurred, and so will not help to detect the spill while it is happening.
The object of the invention is to remedy or reduce at least one of the drawbacks of prior art.
Certain exemplary embodiments can provide a method of determining whether a spill into a marine environment from an offshore installation has occurred comprising: (a) submerging a plurality of cages around and at distances from said installation, said cages containing living organisms fitted with sensors that monitor physiological or behavioral responses by said organisms; (b) transmitting online, real-time signals to a measuring station; (c) 2a comparing signals from said cages to each other and to known patterns of response of said organisms; and (d) determining whether a response by said organisms is caused by a spill from said installation and thereby discriminating from responses caused by other sources or background pollution.
Other embodiments provide a method of determining the effect of a spill on a marine environment physical and chemical sensors and living organisms fitted with instruments are placed at an appropriate distance and position from the object to be monitored, where the response of the living organism,

Other embodiments provide a method of determining the effect of a spill on a marine environment physical and chemical sensors and living organisms fitted with instruments are placed at an appropriate distance and position from the object to be monitored, where the response of the living organism,
3 measured online in real time, is compared with known behavioural patterns, and where upstream and downstream measurements are compared to determine whether a change in response may be caused by a spill from the object, the significance of the real time measurements being validated through sampling of the organisms on a regular basis or as required, in order to analyze the effects on the health of the organisms, biomarkers, for the purpose of assessing the significance of the environmental effect.
In this context, the term "living organisms fitted with instruments" refers to organisms that are fitted with sensors which can measure changes in physiology and behaviour.
As a result it becomes possible to detect a spill while it is happening, and by so doing, it also becomes possible to stop an accidental spill.
The invention allows monitoring of the response of living organisms to a spill. With this one can determine the effect of a spill on the marine environment, and also whether the effect exceeds an acceptable limit.
Furthermore, the extent of the harm caused, both by accidental and permitted discharges, can be assessed. It also becomes possible to evaluate the consequences of repeated spills and the cumulative effect of these.
Typically, a plurality of submerged cages is arranged in a pattern by or around the object to be monitored. The living organism(s) are in the cage and are fitted with the required measuring devices.

Typically, a plurality of submerged cages is arranged in a pattern by or around the object to be monitored. The living organism(s) are in the cage and are fitted with the required measuring devices.
4 The living organisms are monitored by online instrumentation to measure physiological responses to external influences such as pollution. The choice of instrumentation is dependent on e.g. the site of the monitoring, climate and which organisms are the most appropriate for use in a given situation. If the living organism is in the form of shells, it would be appropriate to monitor the opening and closing of the shell, as it has been demonstrated that shells will close when exposed to a certain amount of pollution.
Basically, there are no limitations on which organisms one can select for such monitoring. The organism is selected based on the environment to be monitored. It may be appropriate to use fish and also various species of crustaceans or shellfish, or combinations of these as the living organism.
The physiological responses are compared with known patterns of response, and the upstream response is compared with the response measured downstream of the object to be monitored.
This makes it possible to establish whether the effect is caused by the monitored object or another source.
In order to validate the significance of real time responses, which will principally indicate the potential for damage to the environment, the organisms are sampled on a regular basis or as required in order to validate the state of the organisms' health by use of diagnostic methods, also known as biomarkers, in order to reveal more permanent damage to the organisms.
It has been found that both fish and shells react to pollution with a change in heart rate. Thus it may be appropriate to measure the heart rate of the living organism, among other things because it provides an indication of the food intake of the organism.
Advantageously several measurements may be performed simultaneously, as the development in several separate biomarkers may provide important information when seen as a whole.
The measured values from the living organisms are transmitted to a measuring station which may be located on the object to be monitored, or somewhere else, by means of e.g. a wireless connection.
The measured values arriving at the measuring station can be recorded and assessed manually or by means of equipment that is known per se, and which may for instance trigger an alarm if a predetermined level of measurements or pattern of measurements occurs.
As distinct from prior art methods, in which living organisms in the area must be sampled on a regular basis, the invention requires such sampling only when an indication of a spill exists.

Preferably the fish 6 is in an electrical field that allows measuring of the heart rate, among other things.
